SAFETY-ENVELOP.

SPECIFICATION forming part of Letters Patent No. 743,317, dated November3, 1903.

Application filed June 3, 1903. Serial-No. 159,927. (No model.)

which the following is a specification.

This invention relates to a safety-envelop for use in transmittingvaluable articles through the mails in the same inclosure with aninvoice or communication referring thereto and having thereon warningsigns, or indications, or instructions which will prevent injury to thecontents from the use of handstamps and canceling -machines now commonlyemployed in the postal services.

The improved envelop contains a distinct pocket for the reception of anyarticle of value in one end and at a distance from the end of theenvelop on which the stamp is placed, allowing sufficient space forpostmarking and canceling of the stamp without injury to the articlecontained in the auxiliary pocket. This auxiliary pocket is of lesslength than the main pocket, which extends the full length of theenvelop, and has a sealing-fiap separate and distinct from the flapprovided to inclose the invoice or communication in the main pocket; butwhen the seal of the latter is secured the auxiliary pocket is doublysealed, and the sender is assured of materially-increased security inthe transmission of valuable articles through the mails.

The object. of the present invention is the prevention of thedestruction of valuable articles transmitted through the mails byhandstamps and canceling-machines and 'also to provide a convenientinclosure for sending an article of value in the same package in whichan invoice or communication pertaining thereto is. inserted to have boththe article and in voice or communication arrive together and by thesame mail at their destination.

The improved envelop is so constructed that paper of any thickness maybe economically used in forming the blank therefor, and by a particularfold of the parts, as will hereinafter appear, a double thickness of thematerial of which" the envelop is formed will surround the articleinclosed, thereby reducing the liability of mutilationof the envelop bythe article contained in the auxiliary side.

pocket, particularly if such article has projecting portions or is ofirregular form.

A further advantage in the present form of envelop is that the carryingcapacity thereof is not in the least reduced, but, on the contrary, theformation of the auxiliary pocket increases such capacity and at thesame time strengthens the general structure of the envelop.

In the accompanying drawings, Figure 1 is a plan view of the improvedsafety-envelop shown sealed. Fig; 2 is a similar view of the envelop,showing the auxiliary pocket sealed and the sealing-flap of the mainpocket open. Fig. 3 is a longitudinal vertical section of the envelopcompletely sealed. Fig. 4 is a plan view of the blank from which theenvelop is formed. Fig. 5 is a plan view of the envelop embodying aslight modification in the construction thereof. Fig.6 is a view similarto Fig. 5, showing a part of the one extremity of the envelop brokenaway. Fig. 7 is a longitudinal vertical section on the line 7 7, Fig. 5.Fig. 8 is a plan view of the separate blanks used in forming the envelopillustrated by Figs. 5, 6, and 7.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1, Fig. 4, designates the blank from which the preferredform of the envelop is constructed and comprises three members 2, 3, and4, which are doubled on folding-lines 5 15, defining the oppositeterminals of the primarily middle member 2. The member 4 is constructedto form the auxiliary pocket, which will be hereinafter referred to, andhas an intermediate foldingline 6 and opposite side sealing-flaps 7,which are gummed or supplied with an adhesive substance on one side. Atthe free end of the member 4 is a short sealing-flap 8, also providedwith an adhesive substance on one The member 3 has elongated sidesealing-flaps 9 of a length equal to that of the intermediate or middlemember 2, and at the free end of the member 3 is a sealing-flap 10 ofgreater width than the flap 8; In folding the blank set forth the outerportion of the blank 4 beyond the folding-lines 6 is turned ing thesame. The doubled member 4 in this condition is then bent inwardly onthe foldingline 5, between the same, and the member 2, inwardly againstthe latter member, and said member 2, carrying the doubled or foldedmember 4, is then turned inwardly on the remaining folding-line 5against the member 3, and the sealing-flaps 9 are moistened and bentinwardly and secured over the folded members 4 and leaving both endsealingfiaps 8 and 10 free. By this means an auxiliary pocket 11 isconstructed, as well as a main pocket 12, the said auxiliary pocket 11extending only partially through the length of the main pocket, asclearly shown by Fig. 3. On both the back and front of the envelop aninstruction-space is defined by lines 13 and 14: impressed or printedthereon, the said space being approximately of the same dimensions asthe auxiliary pocket, and on the remaining extremity of the envelop thestamp and address are applied. Within the space defined by the lines 13and 14 printed matter will be inserted instructing the postalauthorities to refrain from using a handstamp or canceling-machinewithin the confines of said space, and thereby avoid injury to thecontents or article disposed in the auxiliary pocket 11.

After the envelop is completed and it is desired to use the same thearticle such as a sample of jewelry, small coin, photographs, seeds, orany other article of value-and the flap Sis then moistened and securedover the mouth of the auxiliary pocket, which is located adjacent to theentrance-opening to the main pocket 12. The invoice or communication isthen inserted in the main pocket, and the sealing-flap 10 is bent overthe flap 8 and secured, as in the ordinary methods of sealing envelops.It will be seen that the sealing-flap 10 covers the flap 11, and in someinstances the invoice or communication may be examined or inspected byreleasing the flap 10 without opening the flap 8, and in some forms ofthe improved envelop the said flap 1.0 may be secured by means capableof being readily unfastened. It will also be seen that the formation ofthe auxiliary pocket 11 in the manner stated provides a double inclosureor two thicknesses of material on opposite sides of the article orsample within said pocket.

The modification illustrated in Figs. 5, 6,

7 and 8 is practically similar to the structure heretofore described,with the exception that the blank shown by Fig. 8 is made in two partsand the members 2 and 3 are integral and separated by a folding-line 15,and the member 4 is detached and has the inner end thereof supplied witha covering of adhesive material, as indicated by the dotted line 16,which is moistened to secure said member to the adjacent end of themember 2. This form of blank permits the envelop to be made of heavierpaper for registry or express purposes or when it is desired to increasethe resistance against breakage of the envelop by the article ormaterial which may be inclosed therein. In folding and completing themodified form of the envelop the same course is pursued as in thefirst-described structure.

The improved envelop will be found exceptionally useful for generalpurposes and may have advertising matter applied thereto, as well as theindications or cautionary instructions to the postal authorities, and itis also obvious that changes in the proportions and dimensions may bevaried at will without in the least departing from the spirit of theinvention.

Having thus fully described the invention, what is claimed as new is Anenvelop, having a main pocket with an end sealing-flap, and an auxiliarypocket within the main pocket and of less length than the latter andalso provided with an independent end sealing-flap of less width thanthe flap of the main pocket, the auxiliary pocket being formed bydoubling the material within the main pocket and having its end entranceadjacent to the entrance of the main pocket, the sealing-flap of theauxiliary pocket, when closed, being covered by the end sealing-flap ofthe main pocket when said latter sealingfiap is secured, and theexterior of the en velop as an entirety having a space defined JOSEPH F.NAUGLE.
